Eco Beaker Lab 1

In exercise one we simulated the arrival of a small group of moose that swam to Isle Royal. The simulation ran over time so that the moose can form a large population on the island. We studied this population of moose before the wolves’ arrival. The simulation ran for 50 years. After the 50 years simulation was complete the data was collected and analyzed.

Answers to Questions:

5.1
ANS: The approximate size of the moose population is 600.

5.2
ANS: The Approximate maximum population size the moose obtained was 930.

5.3
ANS: Simulated Graph: [pic]

5.4
ANS: The exponential growth is approximately from 0 years to 20 years circles in pink.

5.5
ANS: The moose population grew fastest smallest.

5.6
ANS: The carrying capacity is approximately 600. It is labeled in a red K on the graph.

6.1 dN = rmax N (K-N) dt K

ANS: “dN/dt” in the equation above is a differential calculating notation that represents instantaneous change in population size (N) over time (t).

6.2
ANS: When the population size (N) approaches the carry capacity (K) and N=K then the equation is rewritten as such:

dN = rmax K (K-K) dt K

6.3
ANS: Therefore when (N=K) then dN/dt = 0. When dN/dt = 0 then the population stops growing at its maxima per capita rate and stops growing.

...Lab One: Design a Research Project
Hypothesis: Jewelweed juice speeds up healing of the rash caused by Western Poison Ivy.
Research Proposal:
This study is extremely valuable for the sole and simple reason that approximately 85 percent of the population will develop an allergic reaction if exposed to poison ivy, or poison oak according to the American Academy of Dermatology. As a researcher for a pharmaceutical company, this information will aid in the validity of the claim and marketing of the product. This research will also benefits humanity in general by providing a safe and effective cream as an aid in the healing process after exposure.
Ten subjects will be selected after careful interviews regarding allergies to food, medication, or anything else. A thorough medical history review will be made to ensure healthy individuals participate. Any subject with history of severe allergic reactions of any kind will not be allowed to participate. Subjects cannot not be taking any medications or have signs or symptoms of illness at the start of experiment. Baseline vital signs and blood test will be performed: CBC & Chem 10. The subjects must be able to commit for a period of 21 days, and should not be claustrophobic. The age group will be either males or females ages 18-55.

1. Reconnaissance, Scanning, Gaining Access, Maintaining Access, and Covering Tracks
2. You need to do a lot of reconnaissance like network scanning, social engineering, and dumpster diving.
3. A hacker can use tools like Netcraft and PCHels to report on your domain, IP number, and operating system, tools such as NMap identify your host systems and services, tools like LANguard Network Scanner identify system vulnerabilities, and tools such as AET Network Scanner 10, FPort 1.33, and Super Scan 3 scan your devices to determine ports that are open and can be exploited.
4. A social engineer is a person who smooth-talks people into revealing information such as unlisted phone numbers, passwords, and other sensitive information.
5. Enumeration is a process to gather the information about user names, machine names, network resources, shares and services.
6. Once the attack is done the hacker will cover his tracks by modifying the log files, using Trojans to destroy system logs or replace system binaries at the same time, and other techniques like steganography and tunneling.
7. When covering up their tracks a hacker can use rootkits that can disable logging altogether and discard all existing logs making it a lot easier to do it again.

Pipettes and Std Curve
Ingrid Simons
University of Texas at El Paso
June 12, 2014
Introduction:
Procedures that require very small volumes of DNA and reagents are performed with instruments such as, micropipettes and pipettes. These instruments are used when scientists need to accurately and precisely deliver small volumes of a liquid.
Molecular biologists use very small volumes of liquid at times they are as small as 0.1 µL, in order to do these measurements the use micropipettes. The function of the micropipettes is to act as a plunger when the depressed by the thumb and by its release liquid is drawn into a disposable plastic tip. The liquid is released when the plunger is pressed again (The University of QueensLand). The tip is an important part of the micropipette, each tip is disposable and come in different sizes depending of the micropipette being used. There is three standard micropipettes, the P20 which measures 0.5-20μL, P200 that measures 20-200 μL, and P1000 that measures 100 μL to 1 mL.
An important part of this laboratory was learning how to read the meniscus curve. A meniscus is a curve that is formed at the surface of a molecular substance, such as water, when it touches another material (USGS). Meniscus is caused by adhesion, a result of water’s high surface tension. The glass beaker attracts water molecules, and water molecules stay together, as a result many molecules gather to touch the glass. They will accumulate along......

Lab #1 Analyze Essential TCP/IP Networking Protocols
1. What is the purpose of the address resolution protocol (ARP)? ARP is used to mediate between Ethernet (and other broadcast link-level protocols) and the network layer, or IP protocols. Put more simply, ARP converts IP addresses to Ethernet addresses.
2. What is the purpose of the dynamic host control protocol (DHCP)?
DHCP (Dynamic Host Configuration Protocol) is a communications protocol that lets network administrators centrally manage and automate the assignment of Internet Protocol (IP) addresses in an organization's network.

Lab #2 Network Documentation
1. When you TELNET to LAN Switch 1 and LAN Switch 2, why is it a good idea to first PING an IP interface or port’s IP address? The ping verifies connectivity by sending ICMP echo packets to a host and listening for an echo reply. This will detect if there are any name resolution issues.
2. Why is using Telnet a security risk for an IP network infrastructure?
Telnet sessions are in clear text and programs such as packet sniff can capture passwords and then use them to log into those sessions.
3. How can you mitigate the security risk caused by Telnet?
Intrusion detection is a packet inspection tool that monitors, intercepts and responds to abuse in real time. ICMP inspection permits responses to ICMP packets like ping and traceroute that come......

...Post-Lab Questions
1. What were your controls for this experiment? What did they demonstrate? Why was saliva included in this experiment?
This experiment is looking for amylase in-particular. The first control was a negative control, Water ,this would show there is no Amylase present. The second control would be a Positive control ,the starch solution this would show the presence of the enzyme amylase. The negative control water does not contain starch.
Saliva contains Amylase this is why it is included in the experiment. The saliva is a positive because it turned yellow, this shows no starch left because the amylase broke it all down.
2. What is the function of amylase? What does amylase do to starch?
The function of amylase is to start the digestion proses. Amylase function is to break down starch to sugar.
3. Which of the foods that you tested contained amylase? Which did not? What experimental evidence supports your claim? The cooked rice contained Amylase and the starch solution contained amylase. The water the Apple contained no starch.
4. Saliva does not contain amylase until babies are two months old. How could this affect an infant’s digestive requirements?
Usual babies do not start eating food until three months. The reason there saliva does not contain amylase is because there bodies have not started producing it yet. For there digestion it means they will not break down any starch foods and just pass them trough there......
